| REVISION HISTORY |
| |
| Description: Removed hard tabs from file. |
| |
| Description: Added #define for WMF and IF2, and updated function prototype. |
| |
| Description: Renamed WMF to AMR_WMF, IF2 to AMR_IF2, and added AMR_ETS. |
| |
| Description: Changed output_type to output_format. |
| |
| Description: Added external reference to WmfEncBytesPerFrame and |
| If2EncBytesPerFrame tables. |
| |
| Description: Updated function prototype for AMREncode(). Added function |
| prototype for AMREncodeInit, AMREncodeReset, and AMREncodeExit. |
| Added #defines for TX SID frame formatting. |
| |
| Description: Replaced "int" and/or "char" with OSCL defined types. |
| |
| Description: Moved _cplusplus #ifdef after Include section. |
